EMPROVED MACHINE FOR MAKING METAL, CAPS FOI-l Specification forming part0f Letters Patent- No. ',756, dated Ajril C3, 1860.

To @ZZ 107mm/ it may concern:

Be it known that we, CHARLES DIEDRIoH and WILLIAM T. SLooUM, both of thecity and county of Philadelphia, and State of Pennsylvania, haveinvented certain new and useful Improvements in Machinery for MakingMetal Lids and Bottoms for Boxes, &c. and we do hereby declare thefollowing to be a full, clear, and exact description of the saine,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

Our invention .relates to improvements in machinery in which a punch anddie are used for cutting disks from plates of metal and turning theedges of the disks so as to form the bottoms or lids for boxes, dsc.;and our improvement consists, first, in a chute or conductorhaving abent tongue, inclined side, and a vertical chamber with an opening, thewhole being constructed and arranged in respect to the die of thecutting-punch and the die for turning the edge of the disk, in themanner described hereinafter, vso that the disks after leaving thecutting-die may assume a proper position for the action of theformingdie; secondly, in a device for forcing the lids or bottoms fromthe opening in which they have been formed.

In order to enable others to make and use our invention, wewill nowproceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of thisspecification, Figures l and 2 are side views, partly in section, of amachine for punching and forming the edges of metal disks with ourimprovements. Fig. 3 is an end view, and Fig. 4 a sectional plan.

,Similarletters refer to similar paris throughout the several views.

rIhe frame-work of the machine. consists of a base-plate, A, the fourlegs BB, the plate C, and brackets D and E, all firmly secured together.

F is a vertical shaft turning above in the projection a of the bracketsE, and below in the projection b of the block c, which is secured to thebase-plate A. To the upper end of this vertical shaft is securedabevel-wheel, G, gearinginto a similarwheel, H, on the driving-shaft I,which turns in projections on the bracket E, and which is furnished atone end with a pulley, J, for receiving astrap, and at the opposite endwith a crank, K. This crank is connected by a rod, L, and suitablejointsto the lever M, which is secured to the upper end of the screw N, thethreads of the latter being adapted to threads cut in the overhangingportion of the bracket D. The lower end of the screw is so connected tothe upper end of the square plunger P that the former can turnindependently of the latter, but so that one cannot move verticallyindependently of the other. The plunger lits in and is guided byiaprojection, d, of the bracket D, and is furnished with a circular punch,c, adapted to the circular orifice of the die j", which rests on theplate c within the annular flange h` on the said plate, the flange beingprovided with set-screws for adjusting the die so that its orifice maycoincide with the punch e.

Q is a rod sliding in the blocks c and t' (secured to the base-plate A)and operated by an eccentric, B, on the vertical shaft F, the saideccentric fitting into a recess formed in one end of the rod, theopposite end of which is provided with a circular die fitting snugly butmoving freely in the lowestend of the chute S, which will be moreespecially referred to hereinafter. A rod, t, passes through a centralopening` in the rod Q and its die q, the rod tbeing cranked or bent att, and the bent portion passing through a slot, a, in the rod Q, fromwhich point it takes a direct course toward the shaft F, where the rodis forked, the forked end being arranged to embracethc shaft, as bestobserved on reference to 4. An eccentric or eamn, bears against a pinprojecting from the rod t, and tends, as the shaft revolves, to move therod forward and cause its outer end to project beyond the end of the dieq, a spring, w, tending to draw Jthe rod back when the position of theeccentric will permit it, so that the end of the rod may be withdrawninto the orifice of the die q. The upper end of the chute or conductor Sis secured to the underside of the plate c directly under the die f, theenlarged portion of the opening of which coincides with the mouth ol'the chute, which is provided with a bent tongue, e. The front of thechute is straight and vertical, and the rear inclined to within alimited distance from the lower end, which of this temporary retentionof the rodt. rlhe consists of a vertical chamber large enough to admitthe disk of `metal of the same diameter as the punch c, the chamberserving to maintain the disk in its proper vertical position concentricwith the die q and with the opening x in front of the vertical chamberof the chute, into which opening the die q penetrates a short distanceduring the'movement of the machine. This opening communicates with alarger opening in the cross-bar 1 ,which is'V secured to the frcnt legsB of the machine.

On turning the driving-shaft I the following movements will be impartedto different parts of the machine: First, a vibrating motion of thelever M and its screw N, and consequently a vertical reciprocatingmotion to the plunger l? and its punch e,- secondly, a horizontalreciprocating motion to the rod Q through the eccentric R on the shaft F5' thirdly, a reciprocating motion tothe rod t through the eccentric oon the same shaft F.

Supposing the moving parts of the machine to be in the positionillustrated in Fig. l, the punch e being at its most elevated position,and the rods Q and t receding after reaching the limit of their outwardmovement. The operator places the plate of tin on the die F, when thepunch gradually descends, while the rods Q and t continue to recede. Thepunch e, penetrating the oriice of the die Ffcut-s from the tin plate adisk of the desired size, and this disk falls first onto the bent tonguez, which tends to tilt it on its edge, and thence, guided by theinclined side of the chute, into the lower vertical chamber, where itoccupies the position represented in Fig. 2, both the rods Q and t beingso far withdrawn from the chamber as not to interfere with the tendencyof the disk to assume its proper vertical position ready to be actedupon by the die q. The punch e now begins to rise and the rod Q to moveforward, the rod t being for the present held back by the spring w, theposition or form of the eccentric being such as to admit die qcontinuing to move forward strikes against the face of the tin disk and,forcing the central portion of the latter into the opening xin front ofthe lower end of the chute S, turns the edges at right angles to theface of the disk, thus forming the desired bottom, cap, or'

lid, which adheres to the opening in which it hasbeen formed until therod t advances,pushes the lid from the position in which it has beenretained into the enlarged opening of thecross-bar y, from whenceit-falls into any suitable receptacle.

The operating parts of the machine have now assumed the positionrepresented in Fig. l preparatory to a repetition of the above describedmovements.

lt will be understood that the die gis slightly less in diameter thanthe opening x, and that the inner edge of this opening and the edge ofthe die are slightly blunt, so as to prevent any cutting of the diskduring the formation of the lid or cap.

l/Ve claim as our invention and desire to secure by Letters Fatentl. Thechute or conductor S with its bent tongue z, its inclined side, verticalchamber, and opening ar, the whole being constructed, substantially asset forth, and arranged in re` spect to the die f of the punch c and thedie g of the rod Q, as specied.

2. The rod Q and its die q with the central opening for the rod t, theWhole being arranged in respect to the vertical chamber, the chute S,and its opening x, and operating as and for the purpose herein setforth.

In testimony whereof we have signed our names to this specication in thepresence of two subscribing witnesses.
